AUGUSTUS W. IDICKERSON, OE DET BOIT, MICHIGAN.

AUTOMOBILE-HOOD.

Application filed September 27, 1916.

To alZ whom it may concern.

Be it known that I, Ancns'ros N. Dioknn son, who am a citizen of the United State residing at Detroit, county of Wayne, tate of Michigan, have invented a certain new and useful Improvement in Automobile- Hoods, and declare the following to be a full. clear. and exact description of the same. such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to hoods for automobile engines and consists in certain features of construction in the joints thereof as hereinafter described and pointed out in the claims.

In the drawings,-

Figure 1, is a plan view of the hood when assembled and closed, dotted lines showing the features of construction.

Fig. 2, is a plan view of portions of the hood with the two halves thereof separated and detached from the covering of the radiator.

Fig. 3, is a cross-section of Fig. 1. on the line CC.

Fig. 4, is another cross-section of a portion of the two halves of the hood when raised at an angle to each other.

Fig. 5, is a sect onal view adjacent to the hinge, showing the hinge construction ot the two halves at the end thereof.

Fig. 6, is a perspective view of one of the hinges.

Fig. 7, is a perspective of one of the elements of the hinges and will answer for the other element except that they are simply reversed, rights and lefts.

Fig. 8, is a plate with which the elements of the hinges interlock.

Similar letters refer to similar parts.

In the drawings. A represents the frame ofan automobile, B. the radiator cover, D, the cowl against which the hack portion of the hood abuts. E, E represent the two halves forming the hood proper. The two halves E, E of the hood abut together by reason of depressed rectangular alternating opposite sections, as shown in Fig. 3, at F, G. These opposite sections form tongues which, by reason of their depressions or offsets equal to the thickness of the hood enable the two halves to come together with Specification of Letters Patent.

Patented Nov. 13, 1917.

Serial No. 122,527.

a smooth upper surface, each tongue lying underneath the shell of the opposite half of the hood, as shown in Fig. 1, in conjunction with Fig. 3. it is obvious that so far as these interlocking tongues are concerned the two halves of the hood can be separated by simply drawing them apart.

In order to hold the iood in position upon the automobile, 1 provide two hoodsupporting-plates H, such as shown in Figs. 6 and 8, respectively, having a stamped center strip, curved in cross-section to form a part of a pivot bearing; and upon each side of the center strip two rectangular notches h, it. These supporting plates may be attached by rivets, or otherwise, permanently to the radiator cover, and centrally on the cowl, being rights and lefts as shown in dotted lines in Fig. 1, and as shown at the radiator end in Fig. 2.

Attached to the cover at each end respectively and adjacent to the meeting edges are the segmental h nge arms shown in Figs. 6 and 7, marked K, K. Each hinge arm has a flat extension is, provided with means for attaching it to the one half of the hood which it is designed to engage, as shown in dotted lines in Fig. 1. Any suitable means for attaching it may be used, such as bolts or rivets, or it may welded thereto. At right angles to this iiat portion 7c is formed a curved arm L. The concavity oi this is adapted to encircle the curved strip of the plate H, when this segmental hinged arm L, of the member K is inserted in the notch in said plate H, as shown in Fig. 6. Upon the extremity of this depressed angular curved part is a stop M.

The similar parts on the hood wing E are marked with the same letter with a prime sign added.

l/Vhen the hood section carrying the part K is in normal position covering the engine, the attached part K, being inserted in the rectangular notch in the supporting plate H, is in position shown in Fig. 6, and by reason of the angularity of the arm L and the curved center strip under the plate H with the stop M coming up against the under side of the plate H, resulting in looking the hood section in position so that no movement can be made except a hinging one.

The hood carrying the attached pieces K and K, as the case may he, can he entirely withdrawn by lifting them out from connection with the plates H (see Fig. 6). In this manner each half of the hood may be separately withdrawn by raising it substantially to a vertical position and leaving the other half of the hood attached to the engine frame and superstructure and in fact without disturbing it. This, in itself, is a great convenience. In large cars where the hoods are jointed, quite frequently it requires two men, one upon each side, to take off the hood and thus allow free access to the engine underneath it. With this structure which I have devised, one man can lift and remove each side separately or restore each side separately to its normal position.

As already stated, the plates II and the parts K, K may be stamped out of material in one operation and in one form only. The apparent right and left feature being due to merely reversing the ends. his makes a Very cheap structure to manufacture.

The mode of operation is sutiiciently obvious from the foregoing description. If it is desired to lift one half of the hood in place,when raising it, it can be turned over in the position shown in Fig. as E, when the lug M will catch onto the plate H and hold the lifted half of the hood firmly in place.

Having thus described my invention, what I desire to claim is:

1. In an engine hood, the combination of a supporting member at the front and a su; porting member at the rear, a pair of hood sections having offset tongues staggered along the meeting edges of the sections and offset to substantially the thickness of material when the hood sections are in closed position, so that the tongues of one hood section will underlie the body of the opposite hood section, and hinging members one on each end of each hood section and detachable from the supporting member when the hood section is in one position in its swinging are.

2. In an engine hood, the combination of a supporting member at front, a supporting member at rear, a pair of hood sections, and a hinging member at each end of each hood section and each hinging member detachably engaging a supporting member but detachable only at a point between the two extremes of the swinging arc of the hood section.

3. In an engine hood, the combination of a pair of hood sections, a supporting plate at front, a supporting plate at rear, and a. hinging arm on each end of each hood section, the hinging arm and supporting plate interengaging so that they are separable only at a point between the two extremes of the swinging arc of the hood-section.

4. In an engine hood, the combination of a pair of hood-sections, a supporting plate at front, a supporting plate at rear, a hinging arm secured to each end of each hood section, and a stop on each hinging arm to limit the opening swing of the hood-section, the hinging arms and supporting plates being arranged so that the same are only separable at a point between the two extremes of the swinging arc of the hood sections.

5. In an engine hood, the combination of a pair of hood-sections, a supporting plate at front, a supporting plate at rear, each supporting plate comprising a center strip flanked by two notches and segmental in cross-section, and a segmental hinging arm attached one to each end of each hood-section, and engaging detachably in a notch of the supporting plate and pivoting around the segmental center strip, substantially as described.

In testimony whereof, I sign this specification.
